+Moreover, to our knowledge, on the one hand, most often the different
+and interesting developments focus on proposals for a partial
+implication index for binary data~\cite{Lermana} or \cite{Lallich}, on
+the other hand, this notion is not extended to other types of
+variables, to extraction and representation according to a rule graph
+or a hierarchy of meta-rules; structures aiming at access to the
+meaning of a whole not reduced to the sum of its parts \footnote{ICI }, i.e. operating as a complex non-linear system. For example, it is well known, through usage, that the meaning of a sentence does not completely depend on the meaning of each of the words in it (see the previous chapter, point 4).
